Student answer (Band 5.0)

The diagram presents how a mechanical arm works, and how the joints that make up the arm function in the same way as those in arm of a human.

Overall, It conatins 7 parts such as motors,gripper, elbow and shoulder. where spray paint, drill holes and weld metal are also used. Base put on ground for stableization.

Firstly, 3 motors are controlled by computer which operates it. Every motor is responsible to manage different parts where one motor handles the shoulder part which raises and lowers the arms. Second motor manage the elbow of machine which helps to move and flexible in different direction. Next, Wrist is used to allow gripper to rotate and flex.

The third motor is accessed to gripper which is built to control the force. There is pivot part at near shoulders which access arms to rotate in different position. To Joint this all parts of machine alternative tools like spray paint, drill holes, weld metal are used.

Task Achievement / Task Response: Band 5.0

The response attempts to summarise the diagram showing how a mechanical arm works and compares its joints to a human arm. However, the coverage of the visual data is incomplete and disorganised. While the introduction mentions the overall function, the body paragraphs miss several core components shown in the diagram, such as the computer precision control, the base, and the pivot. Additionally, the description of how alternative end-effectors function is conflated and imprecise, stating that tools like 'spray paint, drill holes, weld metal are used' to 'joint this all parts'. Because the key features are not fully or accurately reported, the response falls within the Band 5 descriptor for addressing the task only partially with limited development.

Coherence and Cohesion: Band 5.0

The text is divided into four paragraphs, which shows an attempt at structuring an Academic Task 1 response. However, the overall progression is hindered by awkward transitions and confusing referencing. For instance, sentences like 'where spray paint, drill holes and weld metal are also used' disrupt the logical flow of the overview. Cohesive devices are either missing or misused, and referencing pronouns (such as 'which operates it' and 'manage the elbow of machine') are frequently unclear or grammatically disconnected. Paragraphing is present, but internal cohesion is weak, placing the response firmly at Band 4.5 to 5.0.

Lexical Resource: Band 4.5

The vocabulary used is basic and heavily reliant on direct lifting of labels from the prompt (e.g., 'motors', 'gripper', 'elbow', 'shoulder', 'pivot'). There are noticeable lexical and collocational errors throughout the response, such as 'stableization' (stabilization), 'manage the elbow of machine', and 'access arms to rotate'. The student attempts to use less common items related to the topic, but frequent inaccuracies in word choice and word formation cause difficulty for the reader and prevent the text from reaching a Band 6.

Grammatical Range and Accuracy: Band 4.5

The student attempts a mix of simple and complex sentence structures, but control over grammar is weak. There are frequent errors in verb agreement, tense, and article usage, such as 'Overall, It conatins', 'Every motor is responsible to manage', 'Base put on ground', and 'To Joint this all parts'. Punctuation and capitalization are also erratic, as seen with commas and spacing. These persistent grammatical errors frequently impede communication and place the response at Band 4.5.
